What nerve is damaged in Erb Duchenne Palsy?
The brachial plexus is a network of nerves that conducts signals from the spine to the shoulder, arm, and hand. Brachial plexus injuries are caused by damage to those nerves. Erb-Duchenne (Erb’s) palsy refers to paralysis of the upper brachial plexus.
What causes Erb Duchenne paralysis?
What is Erb’s Palsy? Erb’s palsy is a condition characterized by arm weakness and loss of motion. It can occur in both infants and adults. It’s typically caused by a physical injury during newborn delivery or by traumatic force downward on the upper arm and shoulder, damaging the brachial plexus.
What muscles are paralyzed in Erb’s palsy?
Erb’s palsy or Duchenne-Erb paralysis involves the C5 and C6 roots of the brachial plexus. Palsy of C5 and C6 affects the strength of deltoid, biceps, brachialis, infraspinatus, supraspinatus, and serratus anterior muscles. Also involved are the rhomboids, levator scapulae, and supinator muscles.
What is Erb’s and Klumpke’s paralysis?
Erb’s palsy is the result of the upper brachial plexus being paralyzed, while Klumpke’s palsy is the result of the lower brachial plexus being paralyzed. Klumpke’s palsy can involve the muscles in the hand, the flexors of the wrist and fingers, and sometimes the forearm.
Can Erb Palsy be fixed?
Erb’s palsy resolves completely in the first year of life in 80% to 96% of patients and in nearly 100% if recovery begins within four weeks of birth (5).

What is the difference between Erb’s palsy and brachial plexus injury?
Erb’s palsy affects the motion of the arm and shoulder more so than that of the hand and fingers, but any part of the upper limb may be involved. When the lower brachial plexus nerves that control the hand and fingers are injured, it is referred to as total or global brachial plexus palsy.
What causes Klumpke’s palsy?
Klumpke paralysis is caused by an injury to the nerves of the brachial plexus that which may result during birth due to a a difficult delivery. This injury can cause a stretch injury (neuropraxia), scarring, or tearing of the brachial plexus nerves.
Which nerve is affected in Klumpke’s palsy?
Klumpke paralysis is a neuropathy of the lower brachial plexus which may be resulted from a difficult delivery. Usually, the eighth cervical and first thoracic nerves are injured either before or after they have joined to form the lower trunk.
How is Erb palsy treated?
